Laparoscopic radical prostatectomy compared to open radical prostatectomy: Comparison between surgical time, complications and length of hospital stay.

Introduction: There are very few articles comparing open radical prostatectomy (OPR) with laparoscopic radical prostatectomy (LRP).

Objetives: To compare the surgical time, the postoperative complications and the hospital stay in patients with localized prostate cancer treated with ORP or LRP.

Material And Methods: Comparison between two patients cohorts (312 with ORP and with 206 LRP) between 2007-2015. Postoperative complications were collected as defined in to the EAU Guidelines recommendations and they were classified according to the Clavien-Dindo classification. To compare the qualitative variables, we employed the chi-squared test and ANOVA for quantitative variables. We performed a multivariate analysis using logistic regression with dependent qualitative variables and a lineal regression with dependent continuous variables.

Results: The mean duration of ORP was 3:05hours and 4:35hours for LRP (p=.0001). The 26.4% of the patients presented any postoperative complication. 31.2% of ORP and 19.3% of LRP (p=.003). The mean of hospital stay was 4 days. In ORP group was 4 days in contrast to LRP with 3 days (p=.008). The LRP (p=.0001), lymphadenectomy (p=.02) and nerve-sparing (p=.01) were independent predictor factors of extension of surgical time. LRP was a protector independent factor of complications (OR=0.48 p=.007). The type of prostatectomy didn't influence in the length of hospital stay.

Conclusions: LRP showed higher surgical time, less complications and it didn't influence the hospital stay.
